New world efficiency record for perovskite solar cells

摘要

The allure of perovskites and theirrnpotential impact on solar energyrngeneration is growing. Flexible,rnsimple to make and cheap tornproduce, they could offer muchrnreduced costs in solar cellrnmanufacture. Their downfall is lowrnefficiency and durability. However,rnthis is a relatively new technologyrnand engineers at UNSW in Sydney,rnAustralia have moved itsrndevelopment forward with a newrnworld efficiency record.
